Room 404: Erotic Massage: Self-Massage Not Working (Workarounds)
Short answer
Suggested fix (unconfirmed): Purchase the required self-massage skill first. Alternatively, hold down the left mouse button while placing your hand on the character, then press the middle mouse button.
The problem
I'm having some trouble with the self-massage interaction. The game says that I need to press the mouse wheel (middle mouse button) to start it, but nothing happens. I've tried pressing it both before starting the interaction and while the interaction is already active, but I can't figure out what I'm doing wrong. Has anyone else experienced this issue or knows how to fix it?
